Involvement of insulin-like growth factor binding protein-3 in peroxisome proliferator activated receptor gamma-mediated inhibition of breast cancer cell growth
Publication date: Available online 31 October 2014 Source:Molecular and Cellular Endocrinology Author(s): Cindy K. Pon , Sue M. Firth , Robert C. Baxter We have previously reported that insulin-like growth factor binding protein-3 (IGFBP-3), a protein with dichotomous effects on both cell proliferation and cell survival, interacts with peroxisome proliferator-activated receptor gamma (PPARγ) and inhibits adipogenic PPARγ signaling. We now show that IGFBP-3 and PPARγ interact in breast cancer cells, through amino- and carboxyl-terminal residues of IGFBP-3. IGFBP-3 and the PPARγ ligands, rosiglitazone or 15-deoxy-Δ12,...

The circadian clock machinery controls adiponectin expression
In this study, we tested whether the circadian clock helix–loop–helix transcription factors CLOCK and BMAL1 regulate adiponectin expression. We found that adiponectin expression is regulated by the clock through the circadian expression of its transcription factor peroxisome proliferator-activated receptor γ (PPARγ) and its co-activator PPARγ co-activator 1α (PGC1α) in mouse white adipose tissue and differentiated adipocytes. In addition, reconstitution of the core clock mechanism and siRNA experiments in cell culture suggest that the clock directly activates the adiponectin promoter and mediates its expression. I...

Estrogen mediated epithelial proliferation in the uterus is directed by stromal Fgf10 and Bmp8a
Publication date: Available online 7 November 2014 Source:Molecular and Cellular Endocrinology Author(s): Daesuk Chung , Fei Gao , Anil G. Jegga , Sanjoy K. Das To define endometrial stromal-derived paracrine mediators that participate in estradiol-17β (E2)-induced epithelial proliferation, microarray analysis of gene expression was carried out in mouse uterine epithelial-stromal co-culture systems under the condition of E2 or vehicle (control). Our results demonstrated gene alteration by E2: in epithelial cells, we found up-regulation of 119 genes and down-regulation of 28 genes, while in stroma cells we found up-regul...

Oxytocin activates NF-κB-mediated inflammatory pathways in human gestational tissues
Publication date: Available online 14 November 2014 Source:Molecular and Cellular Endocrinology Author(s): Sung Hye Kim , David A. MacIntyre , Maria Firmino Da Silva , Andrew M. Blanks , Yun S Lee , Steven Thornton , Phillip R. Bennett , Vasso Terzidou Human labor, both at term and preterm, is preceded by NF-κB-mediated inflammatory activation within the uterus leading to myometrial activation, fetal membrane remodelling and cervical ripening. The stimuli triggering inflammatory activation in normal human parturition are not fully understood. We show that the neurohypophyseal peptide, oxytocin (OT), activates NF-κB and...

Palmitoleic acid prevents palmitic acid-induced macrophage activation and consequent p38 MAPK-mediated skeletal muscle insulin resistance
Publication date: 5 August 2014 Source:Molecular and Cellular Endocrinology, Volume 393, Issues 1–2 Author(s): Nicola A. Talbot , Caroline P. Wheeler-Jones , Mark E. Cleasby Obesity and saturated fatty acid (SFA) treatment are both associated with skeletal muscle insulin resistance (IR) and increased macrophage infiltration. However, the relative effects of SFA and unsaturated fatty acid (UFA)-activated macrophages on muscle are unknown. Here, macrophages were treated with palmitic acid, palmitoleic acid or both and the effects of the conditioned medium (CM) on C2C12 myotubes investigated. CM from palmitic acid-treated...

NF-κB increased expression of 17β-hydroxysteroid dehydrogenase 4 promotes HepG2 proliferation via inactivating estradiol
In this study, HepG2 cells were used to investigate the role of HSD17B4 in the proliferation of liver cancer cells treated with the NF-κB activator, tumor necrosis factor-alpha (TNF-α), with the inhibitor of NF-κB activation, pyrrolidinedithiocarbamate (PDTC), or with a related specific siRNA. We demonstrated that the human HSD17B4 gene is a target for NF-κB activation in inflammation-stimulated HepG2 cells. HSD17B4 is up-regulated via the binding of activated NF-κB to the distal NF-κB-responsive element via TNF-α stimulation, which then promotes cell proliferation by decreasing the levels of E2 and enhancing the ex...

Inhibition of prolyl hydroxylase 3 ameliorates cardiac dysfunction in diabetic cardiomyopathy
Publication date: 5 March 2015 Source:Molecular and Cellular Endocrinology, Volume 403 Author(s): Yanfei Xia , Luwei Gong , Hui Liu , Beibei Luo , Bo Li , Rui Li , Beibei Li , Mei Lv , Jinyu Pan , Fengshuang An Prolyl hydroxylase 3 (PHD3) is a member of the prolyl hydroxylases (PHDs) family and is induced by hypoxia. It plays a critical role in regulating the abundance of hypoxia-inducible factor (HIF). Its expression is increased in diabetic rat hearts; however, its role remains unclear. We investigated the potential role and mechanism of action of PHD3 in the setting of diabetes-induced myocardial dysfunction in rats. ...

Transmembrane tumor necrosis factor-alpha sensitizes adipocytes to insulin
Publication date: 5 May 2015 Source:Molecular and Cellular Endocrinology, Volume 406 Author(s): Wenjing Zhou , Peng Yang , Li Liu , Shan Zheng , Qingling Zeng , Huifang Liang , Yazhen Zhu , Zunyue Zhang , Jing Wang , Bingjiao Yin , Feili Gong , Yiping Wu , Zhuoya Li Transmembrane TNF-α (tmTNF-α) acts both as a ligand, delivering ‘forward signaling’ via TNFR, and as a receptor, transducing ‘reverse signaling’. The contradiction of available data regarding the effect of tmTNF-α on insulin resistance may be due to imbalance in both signals. Here, we demonstrated that high glucose-induced impairment of insulin-sti...

Glycated albumin triggers fibrosis and apoptosis via an NADPH oxidase/Nox4-MAPK pathway-dependent mechanism in renal proximal tubular cells
In this study, we investigated the effects of GA on fibrosis and apoptosis of renal proximal tubular cells (NRK-52E) in vitro experiments. Our results showed that GA promoted α-SMA, fibronectin (FN) and TGF-β expressions in NRK-52E cells. GA also increased cell apoptosis and stimulated the expressions of pro-caspase 3/cleaved-caspase 3. GA overloading enhanced the phosphorylation of MAPK pathway. GA-induced α-SMA, FN, TGF-β and caspase 3 expressions were completely suppressed by the NADPH oxidase inhibitor apocynin (Apo), the reactive oxygen species (ROS) scavenger N-acetylcysteine (NAC) and the latent antioxidant Astr...

1,25-Dihydroxyvitamin D3 and extracellular calcium promote mineral deposition via NPP1 activity in a mature osteoblast cell line MLO-A5
Publication date: 5 September 2015 Source:Molecular and Cellular Endocrinology, Volume 412 Author(s): Dongqing Yang , Andrew G. Turner , Asiri R. Wijenayaka , Paul H. Anderson , Howard A. Morris , Gerald J. Atkins While vitamin D supplementation is common, the anabolic mechanisms that improve bone status are poorly understood. Under standard mineralising conditions including media ionised calcium of 1.1 mM, 1,25-dihydroxyvitamin D3 (1,25D) enhanced differentiation and mineral deposition by the mature osteoblast/pre-osteocyte cell line, MLO-A5. This effect was markedly increased with a higher ionised calcium level (1.5â...
